COLLAR-STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,560, dated December 1**7, 1889.

' l Application tiled August 27, 1889. Serial No. 322,164. (No model.,l

T0 all whom it may concern:

Be it known that I, GEORGE E. HoYr, ofE the city and county of San Francisco, Statey of California, have invented an Improvement' in Collar-Stuffing Machines; and I herebydeclare the following to be a full, clear, and exact description of the same.

With straw oriilling, by which they are properly shaped.

broken away to show the interior.

a vertical section taken through the hopper at right angles With the horizontal driving-I shaft. Fig. 3, Sheet 2, is an enlarged vertical section of the upper part of the hopper, 1

showing the gearing by which the stirrers are operated. Fig. 4 is a plan View of the gearing alone.`

This invention is applicable .to that class of machines in which a vertical hopperA is employed having a tube B extending from the lower end, upon Which the flexible leather tube C is slipped, so as to be filled With straw or other material, and thus shaped into the form of a collar. This tube C is held in place by means of a cord D, passing over a pulley E, and having a counter-Weight F sufficient to hold it up,but at the same time to alloWit to gradually move down as the filling is completed. This filling is effected by means of a spiral rod or auger Gr,which is caused to rotate and at the same time is given a vertical reciprocating motion within the tube B and The material within the hopper not to become clogged, by means of the arms II, which are slowly revolved Within the hopper.

My present invention relates to mechanism Vfor actuating these parts.

1 end is a pulley J, around which passes a belt My invention relates to a machine which is` intended to stuff the bodies of horse-collars K from the source of power, and by this means the shaft I is rotated. Upon this shaft I is fixed a beveled gear-wheel L, and

Y i this engages with a pinion M on the upper It consists of a vertical hopper, a rotary and reciprocating auger, by which the filling ma-g terial is forced into the collar, and a mechanism by which the double motion of the fill-i ing-auger is produced, and by Which the n1a terial is properly stirred and loosened up, together With certain details of construction, all `of which Will be more fully explained by referenced to the accompanying drawings, in. .which- V Figure l is a perspective view of my apl.

paratus, a part of one side of the hopper- Fig. 2 is end of the auger G or an extension-shaft N, which is united to it by a suitable coupling and extends up to the upper part of the hopper, as shown. I prefer to use this coupling instead of making the Whole in one piece, so that when the auger becomes Worn or in any Way disabled it may be easily uncoupled and replaced Without removing the other portions of the apparatus.

The upper end of the rod N has ahead P, which extends up through the lower part of a yoke Q, and is allowed to turn loosely around in a socket in which it lies, but it may at the same time receive a vertical motion. l

essary vertical movement for stuffing pur poses The upper end of this link or yoke has an extension R, by Which it is connected with a rocker-ar1n S, Which is fixed to ashaft T, journaled above the hopper, as shown.

Upon the outer end of this shaft is another rocker-arm U, which is connected by a pitman V with a crank-pin at the outer end of the shaft I, and through this a rocking motion is communicated to the shaft T, and through that a reciprocating motion, by which the rod N is caused to rise and fall, at the same time being rotated by the gears L and M,l as ab've described. The gear M has a hub extending doWn through the plate WV, and'hav-a ing a groove or channelX formed in it,which the pin or projection Y fits, and this prevents the pinion from rising and falling with the motion of the rod N.

In order to rotate the stirrers II, they are secured to a head a upon a tube Z2, which ex-v y tends down around the shaft N. This tube has its lower end supported in a journal-box c, which allows it `to turn. 'lhe upper end has a head d, turning within a yoke e, and having a pin f, projecting from one side of it, which is engaged by another and vertical pin g, projecting downwardly from a gearwheel h. This gear-wheel lies within a fixed internal gear fi, which is of larger diameterthan the gearwheel 7L and contains more teeth. The teeth of the two gears, however, are adapted to mesh with each other, and the interior gear 71, is fitted upon an eccentric extension m at the bottom of the hub of the pinion M. This eccentric turns with the pinion M,and simply acts to move every portion of the circumference of the gear 7L successively into contact with the teeth of the stationary surrounding internal gear e'. As the gear 7L has one or more teeth less than its surrounding gear fi, it will be manifest that at the completion of each circuit which the gear h makes within the gear t' it will have fallen behind in rotation a distance equal to the difference in the number of teeth, and by this it will slowly rotate the sleeve b, and with it the stirrers II, moving them backward with just sufficient rapidity to prevent the straw or filling from becoming clogged within the hopper.

The hopper is filled with a suitable material for stuffing t-he collars, and a second 110pper n is hinged to the side of it, having a rope o passing over a pulley and connected with it, and extending down to a point within reach of the operator, so that whenever the hopper A is becoming emptied of material by raising the outer end of the swinging hopper n its contents may be discharged into the hopper A without stopping work.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a collar-stuffing machine, a vertical hopper and a rotary reciprocating auger, a tube extending downward from the hopper and adapted to receive the collar-tube which is fitted over it, in combination with apinion through which the au ger-drivin g rod extends, a gear-wheel mounted uponahorizontal shaft engaging said pinion, so as to produce a rotary motion thereof, a yoke in which the head of the auger-driving rod is swiveled, and a rocker-shaft and rocker-arms connected directly with the yoke, whereby a vertical reciprocating motion is transmitted to the auger, substantially as described.

2. In a collar-stuffing machine, a containing-hopper, the horizontal shaft extending across the upper part, a gear-wheel fixed upon said shaft within the hopper, and a crank-wheel upon the outer end, a pinion with which said gear-wheel meshes, a rod carrying the stuffing-auger, which projects into a tube at the bottom of the hopper, said rod being square and extending through a pinion by which it is caused to rotate, and having a head swiveled within a yoke, and a second shaft journaled upon the hopper above the first-mentioned one and having rocker-arms, one of which is connected with the crank-wheel upon the first shaft and the other with the yoke, whereby the latter is reciprocated so as to give the auger a vertical motion while it is rotated by the gear and pinion, substantially as describe d 3. In a collar-stuffing machine, a containing-hopper having an extension-tube, a reciprocating auger, and a power-shaft having a gear, a rotary pinion M, having the eccentric at its lower end, a gear-wheel fitting loosely around said eccentric and capable of being moved around in a circle by the throw of the eccentric, an internal gear surrounding the first-mentioned gear-wheel, having teeth that mesh with it and having a diameter'sufficiently larger to allow the interior gear to travel around within it, a pin connecting said interior gear with a sleeve surrounding the extension of the collar-stuffing rod, and arms connected with the ends of this sleeve and receiving motion from the gear and sleeve, substantially as described.

In witness whereof I have hereunto set my hand.

GEORGE E. I-IOYT. \\Titncsses:
